Abstract
A method of engine determination is used in an electronically-controlled automatic transmission system. A transmission controller is capable of determining the particular engine model by data sent by the engine controller. The method includes determining whether the data received equals a first predetermined engine model byte stored in RAM. If not, the method determines whether the data received is valid. If so, the method determines whether the data received equals a second predetermined engine model byte stored in EEPROM.
